Welding-equipment manufacturer Miyachi Unitek Corp.has introduced a versatile series of tabletop hot-bar reflow soldering systems for reflow soldering, heat-seal and/or ACF bonding, hot-bar bonding and heat-staking applications.

Kamlakar Rajurkar, a professor in the Department of Industrial and Management Systems Engineering at the University of Nebraska, agreed that sinker EDMing is the preferred method for creating micromolds. “Sinker EDMing, because of its ability to generate sharp corners and machine hard materials, is a predominant micromold machining technology. It is widely used either as a stand-alone technology or in combination with other technologies.” 

Meggitt Sensing Systems recently unveiled its Endevco® model 25A as the world’s smallest ISOTRON® (IEPE-type) piezoelectric accelerometer. Designed to support high-reliability vibration measurement requirements on very small structures and objects, the accelerometer weighs 0.2 g.
